Summarized from the [StackOverflow report here](https://stackoverflow.com/questions/73901263/gurobi-build-issues-with-drake). See our `copy_or_link` logic here: https://github.com/RobotLocomotion/drake/blob/50ad42def05240ad45875dc4137e7a1bf128c04c/tools/install/installer.py#L143-L147 When installing twice in a row, we can overwrite _files_ but not _symlinks_. The `copy2()` function overwrites `dst`...
Per #18004, we should refresh the Ubuntu Provisioned images to use Bazel 5.3.1. Since we have test coverage of 5.3.1 via Unprovisioned already, there is no particular hurry here --...
As it stands today (as of v0.38.0), Ubuntu 18 users must know to install `libpython3.6 python3-tk libx11-6 libsm6 libxt6 libglib2.0-0` by following our documentation at https://drake.mit.edu/pip.html. Similarly for Ubuntu 20....
Per #7451, we don't allow `#include ` in any headers, because we want to insulate our end-users from Drake's choice of VTK. However, this doesn't fully protect users, because we...
Given more than one [`Trajectory`](https://drake.mit.edu/doxygen_cxx/classdrake_1_1trajectories_1_1_trajectory.html) objects, it would be convenient to allow for stacking them. For vstack semantics, imagine one trajectory for a left arm and one trajectory for a...
I wonder if our coverage builds are slow(ish) in part because they are collecting too much of a report? Generally when I'm running a unit test under coverage, I only...
The frequency of builds dying due to https://github.com/bazelbuild/bazel/issues/12010 has increased in recent days, most particularly due to https://mirror.bazel.build/openjdk/azul-zulu11.37.17-ca-jdk11.0.6/zulu11.37.17-ca-jdk11.0.6-linux_x64.tar.gz.

As documented at https://drake.mit.edu/pip.html, prior to `pip install drake` on Ubuntu Focal 20.04, the user needs to upgrade their pip. If they forget to do this, the error message is...
**Is your feature request related to a problem? Please describe.** We currently offer a generic `MathematicalProgram::AddConstraint(Expression, lb, ub)` function that's useful for prototyping: https://github.com/RobotLocomotion/drake/blob/7233a94a7eb96306422f75cd2f12d426a57a9160/solvers/mathematical_program.h#L1280-L1287 The user can pass any symbolic...
